TDcoSim 1.1.0
Release 1.1.0
Highlights
- Increased user flexibility w.r.t. DER placement, and voltage ride through.
- Compatible with pvder 0.2.0.
Major Features and Improvements
- Ride through refactoring based on configurable thresholds:
"LVRT":{"0":{"V_threshold":0.5,"t_threshold":1.0,"mode":"momentary_cessation"}}- Configuring unique DERs at each node using
PVPlacement:
"PVPlacement":{"50":{"derId":"50","powerRating":50,"pvderScale":1}}- Exposure of DER settings through
derIdand DER configuration file:
"50":{"circuit_parameters":{"Rf_actual":0.002,"Lf_actual":25.0e-6, "C_actual":300.0e-6}}Behavioral changes
-
Ride through: There are two modes for each threshold.
momentary_cessation: Power output reduced to zero temporarily
mandatory_operation: Try to maintain rated power outputIn all the modes, once the
t_thresholdtimes are breached, the DER is tripped (i.e. power output reduced to zero permanently). The config will be expected to work with any number of elements (>0) in theLVRTandHVRTdictionaries. -
If
initializeWithActualis True,PNominalandQNominalat each feeder node will be initialized with the actual power output from DER at 100 % insolation. If False, they will be initialized with rated apparent power output of DER.
Breaking Changes
Following breaking changes were introduced in the config file:
- Replaced keywords: power_rating replaced with powerRating, voltage_rating replaced with VrmsRating replaced with, SteadyState replaced with steadyStateInitialization
- Removed keywords: V_LV0/1/2,t_LV0/1/2/_limit,V_HV1/2,t_HV1/2_limit,VRT_INSTANTANEOUS_TRIP,VRT_MOMENTARY_CESSATION,
Bug Fixes and Other Changes
- Fixed the handlers not found warning from logger when DER instances are created.
Backwards-Incompatible Changes
- Not compatible with pvder 0.1.0.
